Stock I ran 181rwhp.

With the Hiper, Toyomoto Header, Intake your looking at 195-202max

We dynoed a car with a similar setup (injen, toyo headers, Dragger) we got 197rwhp

185rwhp/194rwtq - 02 manual

you might want to change the title to something more grammatically correct

Do you have an Auto or Stick? My car is an auto and dyno'd @ 176 rwhp with my HKS Hiper which is about 7-8 rwhp than a standard auto.
